Application med August 14, 1923. semaine. estesi` l an improved hea-ter particularly adapted to be used for tire places.

An important object of the invention v:is to provide a direct heat and an indirect heat together with means whereby the di'- rect heat' 'may be delivered to the room or shut oif therefrom and the fumes delivered to a. flue.

Another'object is to circulate theheat currents in such a manner as to derive the greatest advantage therefrom.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following speciication and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Fig. 1 is a front elevation of a heater constructed in accordance with my invention,

Fig. 2 is a longitudinal vertical sectional view of the heater,

Fig.'v 3 is an end elevation,

Fig. 4 is a transverse vertical sectional View taken on the line 4 4 of Fig. 2,

Fig. 5 is an enlarged detail of one of the end lues,

Fig. 6 is a plan view of a modified form; and

F ig. 7 is a partial front elevation ofthe Same.

In the drawings the numeral 10 designates a tire chamber having its front side open. The fire chamber is surrounded on each side and back by a vertical air chamber or flue 11. The front of the air chamber is covered by an arched grille 12. The tire chamber has a converging top 13 merged at each side into diverging ducts or pipes 14. The top 13 has its front edge 'se'- cured to the lower edge of the lintel of the arch and admits air above said top. The vertical legs or sides of the grille admit air to the chamber 11 from which it passes up and around the pipes 14 and mixed with the air admittedabove the top 13, asis evident from Fig`.'4.

The pipes 14 are inclined upwardly-,but have their ends-directed' hori'zontally'to slip into the lower collarsv 15 ofverticahend lues 16. An upper' cross `chamber 17 surmounts the chamber'll ian'd the elements '13, 14 and 1G aredisposedin thecliamber'17.l The rear walls of the chambers 11and 17 may becontinuous.

The endk tluesare' sni`aller'th'an` the'transversier area of the chamber 17. The front plate 18 of each flue forms the-closure for the end of the chamber 17 and' these plates are exposed on the sides 'of thechimney or pilaster into' which the lchambers are set andthe fire chamber mav be conducted directly through the pipes 14, flues 16, pipe 20 and fluev 22. y

Louver slats 23 are pivoted intheplates 18 in the upper and lower sections and when opened deliver the heat currents from the chamber 10 directly into the room in which the plates are exposed. Inclined ducts 24 arranged in staggered relation (Fig. 3) extend through the end ltlues between the lower sections and thus the indi'- rect heat currents provided` by the air entering the chamber 11 and a circulating around the pipes 14 and 20 in-the chamber 17, are delivered through the said ducts to the room.

It will be seen that the heater may be installed in a chimney or a pilaster may be built in a room which doesnot have a flue. Only the grille 12 will be exposed on the front and theplat'es 18 on the sides. A suitable gas, wood, coal or other fire may be provided in the chamber 10, the gas only being usable where there is no chimney Hue;

The air from the various rooms is drawn in through the grille 12 into the chamber 11 and is warmed by indirect heat from the tire. The heated air currents from the chamber 11 pass up into the chamber 17. Air also enters the chamber 10 and is directly heated by the tire. rEhe air from the chamber passes into the top 13 and is delivered into the pipes 14 from which it passes into the end flues i opened, some of the heat currents will pass out into the room. The direct heat currents passing through the pipes 14 and 2O and the parts 13 and 16 will heat the indirect air currentspassing through the chamber 17 and escaping through the ducts 24. The chamber 17 will act to cause a heat radiation from the parts 13, 14, 16 and 2O and thus obviatc overheating.

As a precautionary means a iiue 25 may be led out of the pipe 2O through the top of the chamber 17, instead of the flue 22, as is shown in Figs. 6 and 7. In chamber 17 a perforated collar 26 surrounds the lue 25 and permits a passage of air tor cooling the flue.

Various changes in the arrangement and structure of the di'tlerent elements as well as modications and alterations, may be made Within the scope of the appended claims.

What 1 claim, is:

1. In a heating device, a tire chamber, an air admitting chamber contiguous to the tire chamber, a cross air chamber above the air chamber and connected therewith, conductors for the currents from the tire chamber passing through the cross chamber, and means for delivering the heated air from the cross chamber.

2. In a heating device, a `[ire chamber, an air admitting chamber contiguous to the tire chamber, a cross air chamber above the air chamber and connected therewith, conductors for the currents from the tire chamber passing through the cross chamber, and end iiues connected with the conductors, and means for passing the air currents from the cross chamber through the end iiues and delivering them.

In a heating device, a tire chamber, an air admitting chamber contiguous to the tire chamber, a cross air chamber above the air chamber and connected therewith, conductors 'tor the currents from the 'tire chamber passing through the cross chamber', means for delivering the heated air from the cross chamber, and means for delivering into the room a portion of the currents passing through the conductors.

Lacasse 4. ln a heating device, a fire chamber, an air admitting chamber contiguous to the tire chamber, a cross air chamber above the air chamber and connected therewith, conductors ior the currents from the tire chamber passing through the cross chamber, end lues connected with the conductors, and means for passing the air currents from the cross chamber through the end ilues and delivering them, and means tor delivering into the room a portion ot the currents passing from the conductors through the end tlues.

5. ln a heating device, a [ire box for directly heating air current, a surrounding chamber for indirectly heating air currents,

a heating chamber receiving the indirectly heated air currents, end fines receiving the directly heated currents, a means for conducting the directly heated air currents from the end tlues, means in the end liues for discharging a portion of the directly heated air currents therefrom into the room, and means for conducting the indirectly heated air currents, from the heating chamber through the end lues and delivering the same into the room.

6. 1n a heating device, a tire chamber having an open Afront, an air chamber surrounding the iire chamber on three sides, -a grille covering the front of the air chamber, a laterally extending heating chamber into which the air chamber discharges air conductors diverging from the top of the lire chamber, end tlues at the ends vot the heating chamber connected with the conductors in the heating chamber, means for conducting currents from the end flues to a chimney Hue, means for optionally discharging air currents vtrom the end flues into the room, and means for conducting air currents trom the heating chamber through the end lues.

7. In a heating device, a ire chamber having an open front, an air chamber surrmmding the lire chamber on three sides, a grille covering the front of the air chamber, laterally extending heating chamber into which the, air chamber discharges air conductors diverging from the top oi' the iire chamber, end Hues at the ends ot' the heating chamber connected with the conductors in the heating chamber, plates closing the ends of the heating chamber and Athe end hues, a cross counecting pipe extending between the end tlues in the heating chamber and having a flue outlet, louvers in the end plates, and ducts passing through the end plates and the end il ues from the heating chamber.
